This is a comparison of the best single 10min sub, taken from Wallaroo, compared to the best single 10min sub, taken from Eagleivew, of the same galaxy. These are both
raw images without darks or flats applied, straight off the same camera, taken through the same telescope and filter. No image processing has been done, just a histogram
balance, to match the core brightness in the two crops. It is very clear that the sky is darker at Eagleview and with a measured FWHM as low as 1.518" for this data set
there is more detail visible in the galaxy as well as more faint background galaxies discernible, due to the lower sky glow and superior atmospheric stability or seeing.

Of the 17 sub frames taken from each site, both collected over two seperate nights, all of the subs taken from Eagleview were of identical quality, while the quality
varied significantly in those taken from Wallaroo, all were noticeably softer than the sub in the comparison, further evidence of the stability of the skies over Eagleview.
